I know alloottt of you will be against me doing this but next week i am going to start taking testosterone, only for a few months tho. I started lifting when i was fourteen. I also weighed 160 lbs. I am now 16 and only weigh 170 lbs. its taken me 3 years to gain 10 lbs (that is also using protien). So I talked to my Weights Teacher (also a football coach) and he told me he isn't all for it but if i am going to take it, to not take it for too long. So now that i am 16 and will be getting a big growth spirt, i am goign to add to it with some testosterone while i am in weights class for two months (which means i will be lifting every single day excpet weekends)
